.net 9 Azure devops pipeline what MSHosted agent to use

[gabsamples6]

Hi,
trying to see if I can build our .net 8 app using .net 9 but I cannot see any ms hosted agent using .net 9.
Am I missing something ?

thanks

Same here, it looks like .net 9 is not available yet in the 'windows-latest' hosted agent.
If you really need to support .net 9 you can install it manually adding these lines to the yaml

• task: UseDotNet@2 #This is needed until windows-latest hosted agent will support .net 9
  inputs:
  packageType: 'sdk'
  version: '9.0.100'
  installationPath: '$(Agent.ToolsDirectory)/dotnet'

@LucaDN66 thanks for your reply and apologies for late response on my side - "Few days off"..

Thanks for that

Just upgraded to .net 9 and am now facing the error
error XA0031: Java SDK 11.0 or above is required when using .NET 6 or higher. Download the latest JDK at: https://aka.ms/msopenjdk
Although I have a build step that sets the java version
- task: JavaToolInstaller@0 displayName: 'Use Java 11' inputs: versionSpec: 11 jdkArchitectureOption: x64 jdkSourceOption: PreInstalled

It worked perfectly fine with .net 8.0 but since upgrading to 9.0 I get the above mentioned error.
Did anyone of you face the same error?

we do not have any java installer and our .net 9 pipeline in azure devops works fine with both iOS and android

Thanks for the quick reply. Which agent are you using? Are you calling dotnet publish?

We are using windows-2022

- task: Bash@3
  displayName: Build Android App
  inputs:
    targetType: 'inline'
    script: |
      cd ${{ parameters.clientPath}}
      dotnet build src/${{parameters.clientAppPrefix}}.XXXApp/${{parameters.clientAppPrefix}}.XXXApp.csproj \
        -f "$(NET_VERSION_PREFIX)-android" \
        -c Release \
        -p:AndroidPackageFormat=aab \
        -p:AndroidKeyStore=True \
        -p:AndroidUseSharedRuntime="False" \
        -p:AndroidSigningKeyStore="$(androidKeyStore.secureFilePath)" \
        -p:AndroidSigningKeyPass="${{ parameters.keystorePassword }}" \
        -p:AndroidSigningKeyAlias="${{ parameters.keyAlias }}" \
        -p:AndroidSigningStorePass="${{ parameters.keyPassword }}"

Thanks a lot. Somehow removing the JavaToolInstaller worked.
